This is simple division:

So, plug it into your calculator and you get:

Your answer's that
it takes 4.5 hrs for the surveillance run.
It is neccesary because you cannot subtract them without having a common denominator so you have to rename 4 1/2
Answer:

Step-by-step explanation:
we have the points
(-3,1) and (0,3)
step 1
Find the slope m of the line
The formula to calculate the slope between two points is equal to

substitute the values


step 2
Find the equation of the line in slope intercept form

we have

----> the y-intercept is the point (0,3)
substitute the values

step 3
Find the equation of the inequality
we know that
The slope is positive
Everything to the left of the line is shaded ( The inequality is of the form y > ax+b or y ≥ ax+b)
Is a dashed line (The inequality is of the form y > ax+ b or y < ax+b)
therefore
The equation of the inequality is of the form y > ax+b
The inequality is

see the attached figure to better understand the problem
16pi
Step-by-step explanation:
pi x r² = ans ÷ 4 = Answer for area
Pi×8²=64pi ÷ 4 = 16pi
